Possible Arduino sleep w/ ST shield?


(Michael Sammon) #1

i have been reading extensively about how to make an arduino uno sleep to preserve battery life. Most pages i visit are saying to connect a resistor from RX to pin 2. But is rx reserved for ST shield? im quite a beginner here and somewhat losing my mind :stuck_out_tongue_winking_eye:


Battery-Operated Zigbee or Zwave Relay

will this work with the st shield?

Try looking into SparkCore. They’re made to be connected to the web and supposedly run with relatively low energy when possible.

From initial trials, I found SparkCore connectivity to SmartThings not as user friendly as a ThingsShield - passing information through endpoints rather than directly parsing commands. Given this, I would prototype with a ThingsShield and then port your code to a SparkCore. This is also great because SC is noticeably smaller than a Arduino with a shield attached (4x smaller).

@thegibertchan cant thank you enough for your time in replying on a second question i had. its nice to know in this forum there are many always ready to help :smiley:
ill definitely look into the sparkcore. im using the mini blinds code provided by @wackware. i really need the arduino to sleep bc it has to run off batteries instead having it run ugly off usb’s :wink:
im starting with one and once i have it complete im going to do my 9 other blinds. i will definitely post pictures and instructions once my 2" venetian blinds are fully automated for turning the shades. it will cost each blind about $45, $20 less in cost than buying that jalousier blinds that were talked about in other topics.
